What this calculator does

Use this calculator when you have a tax-inclusive amount and want to isolate the net amount and the VAT portion using an editable VAT rate.

Formula used

Net amount = gross amount / (1 + VAT rate). VAT amount = gross amount - net amount.

Worked examples

If a listed price is $144 and includes 20% VAT, the net amount is $120 and the VAT amount is $24.
This is useful when a platform or invoice shows a tax-inclusive price and you need the pre-tax value fast.

Notes

Reverse VAT math assumes one VAT rate applied cleanly to the entire gross amount.
Mixed-rate invoices or platform-specific tax handling may require a more detailed calculation.
Check local tax requirements when a transaction involves exemptions, cross-border rules, or special products.
